Well, people were trying to understand what happened. AND, I now know what a “horizontal ground loop” is. :-) My late father would be impressed.

It is amazing to watch such a tremendous ship go out of control like that. A fearful sight, I am amazed more passengers weren’t killed.

Usually pilots refer to a "ground loop" -- without the horizontal -- I just added that word as clarification.

"In aviation, a ground loop is a rapid rotation of a fixed-wing aircraft in the horizontal plane while on the ground"

Ground loops were quite common during primary flight training during landing attempts in "taildragger" light planes -- ones that have a tailwheel and no steerable nosewheel. Often no damage was done if the wingtip did not contact the ground.
